What is the most unusual vintage commercial vacuum cleaner?

[lillylux]

The ADVANCE upright vac from the '60's. I have no picture of it, but it looked like a Hoover DAM on steroids. Had a large Lamb cannister type motor in the handle and a separate motor to drive the nozzle. A fairly early bagless I'd say. It had a little pin to attach the cord to one's uniform (to free up the hands I suppose). We had a commercial carpet cleaning concern in my hometown and they used one of these Advance upright vacuums. They also used their shampooing machine.

Don't have picures of them-but NSS M1 copies--the Pacific Steamex and the Alley Cat.A non functional Alley Cat was on EBay for awhile-beleive a member has a Pacific Steamex vacuum.

Tampa, Florida! Haha, Pullman-Holt might be in Tampa, but that chunk of beating-sweeping action was made in North Canton!
